single voltage Flash) with readout protection
and in-situ programming (remote ISP)
– 256 bytes RAM
■ Clock, Reset and Supply Management
– Enhanced reset system
– Enhanced low voltage supply supervisor with
3 programmable levels
– Clock sources: crystal/ceramic resonator os-
cillators or RC oscillators, external clock,
backup Clock Security System
– Clock-out capability
– 3 Power Saving Modes: Halt, Wait and Slow
■ Interrupt Management
– 7 interrupt vectors plus TRAP and RESET
– 22 external interrupt lines (on 2 vectors)
■ 22 I/O Ports

■ 3 Timers
– Configurable watchdog timer
– Two 16-bit timers with: 2 input captures, 2 out-
put compares, external clock input on one tim-
er, PWM and Pulse generator modes (one
only on ST72104Gx-Auto and ST72216G1-
Auto)
